CT Coronary Calcium Score and Angiogram

CT scanning of the heart has developed considerably in recent years and is now a very valuable investigation. It is important to understand the difference between Coronary CT Calcium Scoring and CT Coronary Angiography.

CT coronary calcium scoring is a simple screening test which can help establish the presence of coronary artery disease and help with cardiovascular risk assessment and treatment. CT Coronary Angiography (CTCA) can evaluate the presence, significance and severity of any coronary artery narrowing that might be present. CTCA requires the injection of a ‘contrast agent’.

It is a slightly more complex test and is typically used to investigate chest pain. Your cardiologist can advise you on whether a CT scan of your heart is indicated and if so whether a simple CT calcium scan or a CTCA will be most appropriate. All test results should be treated with caution and interpreted in the context of a clinical assessment.
